" Maybe you know something about young people, and maybe you don't. I, having been one myself once upon a time, know a few things about them. One thing I know is that if you don't want one to do something - for example, go into a room where there's a portrait of an unbearably beautiful princess- saying "It might cost you your life" is about the worst thing you can possibly say. Because then that's all that young person will want to do.

I mean, why didn't Johannes say something else? Like, "It's a broom closet. Why? you want to see a broom closet?" Or, "It's a fake door, silly. For decoration." Or even, "It's the ladies' bathroom, Your Majesty. Best not go poking your head in there. "
